Description

Composite liquid fertilizer

Technical Field

The invention relates to a liquid fertilizer, in particular to a composite liquid fertilizer.

Background

In the midsummer or facility cultivation condition, the condition that the environmental temperature of crops exceeds 30 ℃ occurs occasionally, even breaks through 40 ℃ at high temperature, and the fruits of the crops are easily burnt in the high-temperature weather, commonly called as 'sunscald disease', which is a non-invasive physiological disease caused by strong light of the composite liquid fertilizer; high temperature easily causes the leaves of crops to curl and wilting, affects the photosynthetic crops of plants, and easily causes great damage. In order to provide a solution for solving the problems, the invention mixes the biostimulant which can improve the resistance of crops together and implants a proper amount of calcium, magnesium and silicon elements which are beneficial to stabilizing cell walls and enhancing photosynthesis.

The special protective film is formed by spraying the foliage on the fruits and leaves of crops, so that the burning of ultraviolet rays to the fruits and the leaves is effectively blocked and reduced, calcium, magnesium and silicon elements are supplemented, the resistance is improved, the growth is regulated, and the quality of agricultural products is improved.

Disclosure of Invention

The invention aims at providing a composite liquid fertilizer which comprises the following components in parts by weight: 50-70 parts of woody peat based calcium magnesium fulvate, 10-35 parts of seaweed extract and 10-40 parts of silicon assistant.

Further, the wood peat based calcium magnesium fulvate contains more than or equal to 2.2 wt% of fulvic acid, more than or equal to 7.5 wt% of CaO and more than or equal to 2.5 wt% of Mg 0; the solid content in the seaweed extract is more than or equal to 4.5 wt%, and the organic matter is more than or equal to 12 wt%; the silicon dioxide content in the silicon assistant is not less than 9 wt%.

The preparation method of the composite liquid fertilizer comprises the following steps: weighing the components in parts by weight, stirring woody peat based calcium magnesium fulvate at 50 ℃, adding a silicon auxiliary agent, continuously stirring for 20min, slowly adding the seaweed extract, stirring for 30-50min, filtering, and taking the filtrate to obtain the product.

The composite liquid fertilizer is suitable for fruit trees or vegetable crops, can be applied by flushing or drip irrigation, and can also be applied to leaf surfaces. The dosage of the irrigation or drip irrigation is 2-4L/mu, and the dilution is 300-500 times when the foliage is sprayed.

The compound liquid fertilizer can prevent sunscald, improve crop resistance, prevent wilting, improve peel hardness and luster, has good surface gloss and storage resistance, can prevent fruit deficiency and improve fruit sugar degree; the seaweed extract is combined with silicon, calcium and magnesium, and can stimulate metabolism, improve stress resistance and promote root growth.

The peat is organic mineral resources formed by accumulating and converting dead plant residues in the marsh, is high in organic matter and humic acid content, rich, loose and porous in fiber content, large in specific surface area of the air-permeable and water-permeable charcoals, strong in adsorption and chelation capacity, strong in ion exchange capacity and salt balance control capacity, and is a good crop cultivation medium. The free radical of the peat humic acid belongs to a semiquinone structure, can be oxidized into quinone and reduced into phenol, plays an important role in the oxidation reduction of plants, has higher biological activity and physiological stimulation and stronger drought resistance, disease resistance, low temperature resistance and salt stain resistance, and has very wide application prospect in agricultural production.

Woody peat is peat consisting of woody plant residues. Most of them are formed under the condition of rich nutrition (low-grade) marsh, and their residuum is mainly made up by using birch and spruce, etc. The peat is brown and brown, dark brown, and has a blocky structure. In the woody peat having a low decomposition degree, the raw wood, the roots and the barks can be visually recognized. The woody peat is characterized by high carbon content (up to 60-65%), low content of water-soluble substances, hemicellulose and cellulose, and high content of humic acid and peat wax.

The fulvic acid silicon calcium magnesium liquid raw material extracted and prepared by using the woody peat as the raw material has the efficacy of the biological stimulin and also has the supplement efficacy of calcium and magnesium medium elements.

Calcium has effects of stabilizing cell membrane (calcium is bridging element of phosphate, phosphate and protein on membrane surface), enhancing stress resistance to environmental stress, promoting dry matter accumulation, preventing senilism, improving quality, and prolonging storage period; firming the cell wall (cell wall pectic component, calcium pectin form binding two adjacent cells, strengthening cell wall structure), promoting cell elongation and root growth. Calcium deficiency destroys cell wall bonding and inhibits cell wall formation.

Magnesium is the central atom of the porphyrin ring of chlorophyll, and the photosynthetic carbon assimilation reaction can be carried out only by virtue of the magnesium chlorophyll; magnesium participates in protein synthesis, and is used as a bridging element of a ribosome subunit to ensure a stable structure of the ribosome and provide a place for protein synthesis; magnesium participates in the activation of enzymes: a range of enzymatic reactions all require or rely on magnesium for regulation.

The seaweed extract contains abundant phytohormones and parahormones, the report that indolacetic acid exists in various seaweeds appears as early as 50 s in the 20 th century, and the structures and contents of the indolacetic acid, phenylacetic acid, hydroxyphenylacetic acid and the like in the seaweeds are continuously confirmed, so that the existence of auxin in the seaweeds is further confirmed. The seaweed extract also contains rich active organic matters, a certain amount of amino acids, proteins and trace nutrient elements, and also contains seaweed polysaccharide, alginic acid, highly unsaturated fatty acid, mineral elements such as zinc, iodine and the like which are rare in terrestrial plants and various nutrient substances such as rich vitamins and the like which are specific to marine organisms, and has the functions of improving the yield of crops, improving the quality of the crops and enhancing the stress resistance of the crops.

Silicon is involved in the composition of the cell wall: silicon, pectic acid, polyuronic acid, glycolipid and the like form a compound with strong stability, and the compound is deposited in lignified cell walls, so that the mechanical strength and the stability of tissues are enhanced, and the invasion of plant diseases and insect pests is resisted; silicon affects plant photosynthesis and transpiration. Silicon improves stress resistance, and researches show that: silicon plays an important role in improving manganese toxicity, aluminum toxicity, chromium toxicity and salt tolerance, and can obviously improve the resistance of wheat, cucumber and grape to powdery mildew and the resistance of rice to rice blast.
